Certificates of Kerui Fiberglass Products
Kerui fiberglass products have international certifications including ISO, CE, and SGS certifications. These certifications ensure both the quality and performance of the products. In addition, Kerui has received numerous honors from the refractory and insulation industry as well as local government. Kerui is a reliable fiberglass product supplier with a strong sense of social responsibility. Customers can be assured of purchasing high-quality fiberglass insulation products.
Brief Introduction of Fiberglass Product
The main raw material of Kerui fiberglass insulation products is high-purity glass-forming materials such as silica, alumina, and other oxides. Kerui produces them through advanced high-temperature melting and fiber forming processes. The fiberglass is white or slightly transparent, odorless, and has excellent flexibility. This gives it good toughness, thermal insulation, and durability, making it suitable for a wide range of industrial applications.
To meet different requirements in various industries, Kerui offers a wide range of fiberglass products. Alternative names include glass fiber textile products, high-temperature insulation materials, fiber glass mats, fiberglass boards, and fiberglass ropes.
In addition to fiberglass, Kerui also provides other insulation and refractory solutions, such as Aluminum Silicate Fiber Blanket, Calcium Silicate Board, and Refractory Castables, which can be used together for comprehensive thermal insulation and refractory applications.
Manufacturing Process of Fiberglass Product
| 1. Preparation of Raw Materials | 2. Forming Fiberglass Fibers | 3. Mold and Shape Fiberglass Products | 4. Packaging and Delivery |
The process begins with the preparation of raw materials. The main components are silica, alumina, and other mineral oxides. These raw materials undergo crushing, melting, and mixing to achieve the desired chemical composition and consistency.
- Strict quality control on raw materials;
- Advanced processing equipment for raw materials;
After preparing the raw materials, employees process them into fiberglass fibers. There are two common methods for forming fibers:
- Spinning: The molten glass is spun into fine fibers using centrifugal force or air blowing techniques. Fibers are collected on rotating drums or collection devices to form mats.
- Blowing: The molten glass is forced through spinnerets or nozzles and cooled by air or gas streams, forming fine fiberglass strands.
In the molding stage, the fibers are processed according to the desired application. Common forms of fiberglass products include blankets, boards, mats, papers, cloths, ropes, and tubes. Fibers can be compressed, layered, or woven to achieve the required thickness, density, and shape.
Some projects may require combining fiberglass products with other refractory or insulation materials, such as High Alumina Fire Bricks or Calcium Silicate Boards, to achieve optimal thermal performance.
- Precise molding system
- Highly automatic equipment allows efficient production
After molding, Kerui conducts strict quality control to ensure products meet specifications and standards. Products are then packed according to their form and customer requirements, and shipped to their destinations ready for use in insulation and industrial applications.
- High-quality and fast production
- Safe and on-time delivery
